This can be problem when Studio doesn't recognise a string in one piece, which you can see because the broken blue lines under the source.  There are two fairly straightforward solutions to this depending on the context of your text.

If these are all as you have shown then simply filter on these segments using one of the display filters,then copy source to target and use a simple search & replace to correct the only part that needs translating at the end.

Or use something like the regex auto-suggest provider and convert the string into exactly what you need interactively as you work.  If you give us the proper conversion I can show you how to do this?

PLS Paul!
I would really appreciate that!

I though about option 1 BUT can't build a filter ...

Or ...

What You mean, Paul, by "proper conversion"?

I could tell You: "I need trados canche tel.numbers from a format like 1111 доб.222 into 1111 ext.222" or maybe "I wish it changes 123 факс 45 into 123 fax:45"

BUT ... Here many nubers have so many different formates ... Sometimes they are like 7-495-123 in other cases they are 7(495)123, in a cases 7-(495)-123 etc ... This is a DELIRIUM!

There are so many ... Translating from Russian sentences about "melt traps for radioactive plasma in termonuclear reactor" is being much easier thatn check all these numbers ... 

here is another example ... 
Why should the code 1200 become 1000 ???
Maybe because before there was this case where I transalted ВВЭР-1200 into VEER-1200
But this

... is bad!

ok - let's go with the filter it seems a lot easier.  Can you share the source file?  If you can I can more precise for you, but if not you can try something like this to filter on them all:

The search and replace after copying source to target to get what you need.

Mmmm 
This ^\d stuff is already usefull !!!    Thank You Paul!
I'll have to go deeper in this ...
And in RegEx ...
